File filter: searching a file by name should only find filtered files

In the file table, it could be great if the "filter by name" feature only would consider files visible without typing anything, not all files.

for instance if I want to see all .vhd modified file, I can unselect "unchanged files", and search for .vhd files.

currently smartgit will display all .vhd files even those that are "unchanged" whereas the "unchanged" button filter is activated.
